The quantum computer is on its way, but is society ready for it? Quantum computers have a reputation of being difficult to grasp because of their complexity. This limits society’s ability to envision future applications creating a gap between society and quantum computers. A consortium of 14 knowledge…

The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers,…

The first Leiden Science Family Day on Saturday 6 October was a great success. During the ‘Weekend of Science’ more than 700 visitors, including 350 children, visited the Faculty of Science. With a program full of experiments, lectures, guided tours and demonstrations, visitors were given a glimpse…

On Tuesday 4 September, Martina Vijver delivered the scientific lecture during the academic opening of the Faculty of Science. Martina is professor in Ecotoxicology at CML and would like to have collaborations with colleagues from the Leiden Centre of Data Science. We had a brief interview with her.

Leiden physicists use a new method to measure so-called surface plasmons. Researching these particles could lead to new light-based technology, including faster internet.

The worldwide race to the quantum computer is in full swing. This computer can bring about a breakthrough in discovering medicines and new materials. Leiden researchers, together with the TU Delft, are taking part in the race. There is now a dossier online about their work.

CERN has approved the construction and operation of SND@LHC, a neutrino detector at the Large Hadron Collider. It's a precursor for SHiP, a detector meant to detect dark matter. Leiden physicist Alexey Boyarsky is one of the initiators of both SHiP and SND@LHC.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

Jan Melissen, associate professor at ISGA and editor-in-chief of The Hague Journal of Diplomacy, and his team have been awarded 10,000 euros from the 'Valued' fund. This pilot fund, implemented by the KNAW (Royal Netherlands Academy of Arts and Sciences) aims to increase the interaction between science…

Graphene has held a great promise for applications since it was first isolated in 2004. But we still don’t use it in our large-scale technology, because we have no way of producing graphene on an industrial scale. Leiden physicists have now visualized for the first time how atoms behave in between graphene…

Scientists need individual photons for quantum cryptography and quantum computers. Leiden physicists have now experimentally demonstrated a new production method. Publication in Physical Review Letters on July 23rd.

Is it possible to diagnose diseases using molecular switches? The new international consortium LogicLab will address this question. Leiden chemist Sylvestre Bonnet and Leiden pharmacologist Thomas Hankemeier are involved in the project. LogicLab will run for four years and will receive over 3.5 million…

Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.…

A 35-year-old uranium crystal will not disclose its secret: what causes a dramatic phase transition at 17.5 Kelvin? Thanks to a new artificial intelligence approach, half of the possible explanations are excluded, but the definitive answer remains to be found. 'It is very frustrating', says physicist…

An international collaboration, including Leiden physicist and computer scientist Vedran Dunjko, showed that quantum technology can speed-up the learning process of artificial intelligence (AI). To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

Liposomes – nano-sized spheres composed of fatty molecules – are very promising for vaccination. Bio-pharmaceutical scientist Naomi Benne discovered that the immune response in animal models can be steered by varying the charge of the liposomes. She obtained her PhD degree on 8 September for this research,…

Leiden researchers found a way to measure the tiny forces exerted by pericytes, one of the most elusive, hard to research cell types, which occur in tiny blood vessels. Building on this fundamental science, researchers may eventually find treatments for medical conditions like ischaemia.
